DEMO_5AR4770AG_14W1

Overview

14W 15V 5V SMPS demonstration board with ICE5AR4770AG

This 14.5W demonstration board operates under a wide range input developed with offline SMPS application in mind. It features the new ICE5AR4770AG PWM fixed frequency CoolSET™ with 700V integrated MOSFET in DSO-12 package.

Summary of Features

  • Flyback topology with dual non-isolated output
  • 100kHz switching frequency with discontinuous current mode design
  • Wide-range input from 85~300VAC with line over-voltage protection at 320VAC
  • Output #1: 15V/0.83A
  • Output #2: 5V/0.4A

Benefits

  • High efficiency with frequency reduction from mid to light load condition
  • Robust operation with adjustable line input over-voltage protection
  • BOM savings with integrated error amplifier to support direct feedback on the primary side

Potential Applications

  • Offline SMPS, adapter, main power set-top-box, water/air purifier and TV, auxiliary power for air conditioning, refrigerator, server, PC power and audio
